SHAFAQNA (International Shia News Association)-Takfiri ISIL militants have reportedly executed 250 Syrian soldiers they had taken hostage at an airbase in the northern province of Raqqa.

The killings, the video of which was published on the internet, took place on Wednesday at Tabqa airbase, which was overran by the ISIL Takfiri militants.

Rami Abdel Rahman, the head of the London-based so-called Syrian Observatory for Human Rights (SOHR), said on Thursday that Syrian soldiers captured while fleeing after the ISIL militants overran Tabqa airbase were executed by the terrorists “during the night.”

The base is located some 45 kilometers outside Raqqa and reportedly holds several planes, helicopters, tanks and artillery.

ISIL militants operating against the Syrian government have committed numerous mass executions during the ongoing conflict.

Since the outbreak of crisis in Syria in March 2011, several video clips have been released showing the grisly crimes perpetrated by the Takfiri terrorists against innocent civilians in the crisis-torn country.

ISIL terrorists have been behind many of the deadly bomb attacks targeting both civilians and government institutions across Syria over the past three years.

The ISIL violence has spilled over to neighboring Iraq.

The terrorist group has links with Saudi intelligence and is believed to be indirectly supported by the Israeli regime.
